Message-ID: <9005061648.AA00952@apple.com> Date: 6 May 90 16:47:56 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 85 i sense that you guys weren't entirely thrilled with my multiple 68k approach - though i can't understand why - it is both doable and inexpensive... anyway, the title of this article is correct. thirty-two bit 6502's already exist (and have existed since late '87) the chip that i'm referring to is the arm - acorn risc machine. it is a risc chip with an instruction set deliberately designed around the 6502 - actually the instruction set is a superset of the 6502. it was designed for the archimedes a310 computer in england, which was previewed in the october 1987 issue of byte. the archimedes was designed to be a high-performance replacement of the acorn computer (bbc micro) which uses the 6502 as its main processor. it is also operating system compatible with the bbc micro. how does it perform? well, here's the specs: (I'D ENCOURAGE YOU TO FIND A COPY OF THE OCT '87 BYTE AND SEE THIS MACHINE FOR YOURSELF...THE ARTICLE RUNS FROM PAGES 125 TO 130) THE ARCHIMEDES A310 COMES STANDARD WITH - 1 MEGABYTE OF RAM - 1 3.5" 800K DISK DRIVE - 512K ROM - GRAPHICS: 640 BY 512, 256 COLORS OUT OF A PALETTE OF 4096 - SOUND: EIGHT VOICES, STEREO - PARALLEL PRINTER INTERFACE, RS-432 (RS-422?) SERIAL INTERFACE ACCORDING TO BYTE LAB'S TESTS: ARCHIMEDES COMPAQ DESKPRO MAC SE W/ 386 (16 MHZ) HYPERCHARGER 80287 (10 MHZ) FIBBONACCI 52.4 SEC 53.1 71.6 SIEVE 5.7 SEC 6.0 14.9 SORT 10.0 SEC 5.6 20.6 SAVAGE 91.2 SEC 21.5 8.8 DHRYSTONES/ 4901 3748 2176 SECOND ---- ALL BENCHMARKS WERE PERFORMED IN C. THE ONLY DISAPPOINTING MEASURE WAS IN THE SAVAGE BENCHMARK (MANY NESTED TRIG. FUNCTIONS, LOGS, ANTILOGS, ETC.) WHEN THESE TEST WERE PERFORMED IN THE INCLUDED BASIC LANGUAGE, SAVAGE TIME WAS CUT TO 32.8 SECS. SO THIS SYSTEM MUST COST A SMALL FORTUNE RIGHT?? < EL WRONGO > TRY $1600 US (ABOUT 1000 POUNDS). THE A300 LINE IS, ACORDING TO THE ARTICLE, TARGETED FOR THE HOME AND EDUCATION MARKET. THE A400 LINE WHICH INCLUDES MORE MEMORY, FAST HARD DRIVES AND EXPANSION SLOTS, IS TARGETED MORE FOR BUSINESS AND PROFESSIONAL USE. (YOU REALLY SHOULD SEE THIS ARTICLE - I'M NOT KIDDING) AND FOR YOU COPROCESSOR HATER'S OUT THERE - IT HASNT GOT ANY. ALL GRAPHICS, SOUND AND I/O ARE PERFOMED STRICTLY BY "ARM POWER" (WITH A LITTLE HELP FROM GS TYPE GLU'S) AND AS FOR THE ARM - "IT'S DESIGN DELIBERATELY RESEMBLES A 6502 BROUGHT UP TO DATE WITH SHORT, FAST INSTRUCTIONS AND A SUPERFAST INTERRUPT RESPONSE TIME" THE ARM CAN ALSO ADDRESS 64 MEGABYTES OF RAM. DROOL OVER THAT FOR A WHILE. MARK ORR | "YOU AREN'T GOING TO | BE HAPPY UNTIL YOU $CSB211@LSUVM.SNCC.LSU.EDU | CUT YOURSELF WITH IT!!!" @LSUVM (BITNET) | |
